RE: there is no federal law or Constitutional Amendment that supports such.
That is why we need a Constitutional Amendment to SPECIFICALLY address this issue. That’s what I’ve been saying all along.
We already have one. All we need to do is to actually adhere to it and stop with the political 'policy' of wink, wink... legally, you're not a citizen but we'll "deem" you to be one anyway.
The children of illegal aliens and non-immigrant aliens were never meant to have birthright U.S. citizenship. If their parents actually DO naturalize at some later time, they can acquire U.S. citizenship that way.
